Application filed September 26 ,192); Serial No. i

This invention relates to a surgical instrument which is mainly designed for the treatment of gonorrhoea, but which,eof course, can be used for other purposes, the general 5 object of the invention being to provide means for dilating the walls of the passage to be treated so that the fluid or the like introduced through the instrument will come in full contact with all portions of the diseased parts.

Another object of the invention is to pro vide a head on the inner end of the instrument which is so shaped as to facilitatethe v entrance of'a part of the instrument in the rt to be treated, said head also acting as a stop for preventing the fluid from passing beyond the diseased parts, which would act to carry germs to the parts not diseased. A further object of the inventionis to provide means whereby the fluidcan be caused to circulate through the instrument to irrigate the diseased parts or can be held in contact with the diseased parts for any dey sired length of time.- Another object of the invention is to provide means whereby the expansible part of the instrument can be expanded or contracted from that end of the instrument which is I exterior of that part of the bodybeing I treated.

This invention also consists in certain other features of construction and in the combination and arrangement of the several i ,parts, to be hereinafter fully described, illus- *trated in the accompanying drawings and specifically pointed out in the appended,

. part of the tube 5 and byturning this nut to Figure 4 is a section on line of Fig-- ure 3. I g p y In these views, the numeral 1 indicates the outer tube which is formed with adowne wardly curved front end '2 containing a'valve 3, and the numeral 4 indicates a perforated collar arranged in theinner end of the tube I 1. Theinn'er tube is shown at 5] and has a threaded outer part which passes through a v bushing '6 on the outer end of the tube l and said tube 5 passes through the tube 1 and through the collar and projects a considerable distance beyond the inner end of the tube 1. A substantially conical shaped head 7 .is connected with the inner end of the tube 05 5 and is of hollow construction so that liquid or the like passing through the tube 5 will flow into the head and then pass therefrom through the perforations 8 which di root the liquid toward the inner end of the tube 1. Springstrips 9 havetheirends connected with the inner end of the tube 1 and the head and these strips are so formed that when'the tube 5 is moved outwardly to draw the head toward 'the'tube 1, the strips will 7 assume a bowed shape, as shown in Figure 2, so that they will expand or dilate the walls of a passage in which this partof the device is located. A nut 13 is placed onthe threaded cause it to press againstjthe end of the bushing, the tube 5 will be moved outwardly and thus the spring strips will be expanded. When the nut is turned in the opposite direction, the spring strips and the pressure thereon of the dilated walls of the passage will move the inner tube to normal position, with the spring strips contracted. 7

The outer end of the tube 5 is of substantially funnel shape, as shown at 10, sothat the tapered nozzle 11 of a bulb'or syringe 12 can be inserted therein to force liquid through the tube'5. v

From the foregoing it will be seen that the instrument can be inserted in a passage in the human'body to a'point where the expansible part thereof formed by the strips 9 will come opposite the parts to be treated; Then by turning, thenut 13, the strips will be expanded so as to dilate-the walls of that por- 1 tion of the passage to be treated. Then the relative to the free end of the syringe poiliquid is forced through the tube 5 so that it tion and to expand the walls of the passage will enter the head and flow backwards adjacent the head by flexing the strips.

through the passage 8 into the dilated part of the passage to be treated, after which the liquid will flow through the perforations in the collar 4 and through the tube 1, past the valve 3 to the point of discharge. Thus the liquid comes in full contact with all parts of the diseased walls and by opening the valve 3, the parts can be irrigated as long as desired. By closing the valve, the liquid can be held in contact with the diseased walls as long as desired. After the treatment is fin-.

uid flows back into the tube 1, after leaving the diseased parts, the forward part of the passage is also protected from the'liquid carrying the germs.

As before stated, the instrument is mainly designed for treating'gonorrhoea, especially in males, but, of course, it can be used for other purposes.

It is thought from theforegoing description that the advantages and novel features of the invention will be readily apparent.

It isto be understood that changes may be made in; the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is a V A dilating irrigator comprising a L-shaped tube, one branch thereof'forming a combined handle and discharge portion and the other branch providinga comparatively long syringe portion; to be inserted. in a passage of a person, a control valve in combined handle and discharge portion,'a perforated disklocated in the free end of the. syringe portion and having a centrally arranged bearing opening, abushing formed onthe tube at the bendthereofand having the bore of said bushing in alinement; with the bearingopening, a. second tube slidable in the bushing and bearing opening and having one end flared to receive a syringe, a hollow conical-shaped head formed on'the other end of the second tube and having-discharge openings directed toward the perforated disk, flexible strips connected to the head and to the free end of the syringe portion to be flexed by the movement of thehead relative to the free end of the syringe portion, and a nut. threaded to the; second tube and bearing against; the bushing-for varyingthehead;

In testimony whereof I aflix my signature.
